3. Par ailleurs, le coût des travau

3. Par ailleurs, le coût des travaux sur les RN bitumées est généralement assez élevé du fait, d’une part, des contraintes de spécifications techniques et, d’autre part, de la variation difficilement maîtrisable du prix des intrants (bitume, acier, ciment…). Des efforts sont mis en œuvre pour l’utilisation de nouveaux intrants et de matériaux locaux, mais ils restent pour le moment au stade expérimental

3. on the other hand, the cost of work on the paved RN is generally quite high because, on the one hand, technical specifications and constraints, on the other hand, difficult to control variation in the price of inputs (bitumen, steel, cement...). Efforts are being implemented for the use of new inputs and local materials, but they remain currently at the experimental stage

3. Furthermore, the cost of work on paved RN is usually quite high because, firstly, the constraints of technical specifications and, secondly, the difficult to control variation in input prices (bitumen, steel cement ...). Efforts are made to the use of new inputs and local materials, but they are currently in the experimental stage

3. In addition, the cost of the work is usually RN asphalt quite high, on the one hand, technical specifications and constraints, on the other hand, it is difficult to control the input price changes (asphalt cement, steel, etc.). Work hard to achieve new investment and the use of local materials,But they are still in the experimental stage
